Description

显示器画质图效调整的方法及装置 技术领域
本发明涉及显示器技术领域，尤其涉及一种显示器画质图效调整的方法及装置。
背景技术
在电视机的设计阶段，要进行画质(PQ)图效的调整，由于画质的调整往往比较细微，因此，通常是通过调整一台标准画质样机获得调整数据，再将该调整数据扩展到同型号、同批次的其他机器中。
然而，任何批量的电子产品，其个体间的产品性能都有一定的偏差或离散。即使是两个同型号、同批次的产品，其性能也不能做到完全一致，TFT LCD电视或其它显示器件也存在这样的问题。因为制造精度、质量控制等原因，在批量的产品中，个体间在亮度、色度等方面存在差异。比如，在同型号、同批次的显示器产品中，最大亮度相差近20％，整机γ值从1.8到2.5不等。同一台机器，各灰阶间γ值差别更大。这些差异，将直接影响显示器的画质，如亮度、对比层次等。
显然，由于标准画质样机与批量产品机器间存在的个体差异，将标准画质样机的调整数据扩展到其他机器中，将会严重影响画质的最终达成效果。图效调整可能因此大打折扣，甚至南辕北辙。
为了使批量生产的产品画质图效都能够达到设计之初的标准画质样机的水平，目前都是通过严格控制部品的一致性，缩小批量生产的产品间的性能差距，然而，该方法在实际应用中存在困难，难以真正实现批量生产的产品画质图效都达到标准画质样机的水平。

本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明提供一种显示器画质图效调整的方法。
参照图1，图1为本发明显示器画质图效调整的方法的第一实施例的流程示意图。
在一实施例中，所述显示器画质图效调整的方法包括：
步骤S10，调整待调试样机机芯使预设灰阶下待调试样机整机的γ值达目标值，并将此时机芯的γ值作为所述预设灰阶下的γn值；
显示器类的产品，为了使画质图效相同，在生产阶段要严格控制部品的一致性，缩小批量生产的产品间的性能差距，并以标准样机为标准对待调试样机进行调试，使待调试样机都能达到或接近标准样机的画质图效。当整机的γ值达到使画质处于最佳视觉状态时，即使画质达到目标画质，而整机的γ值包括机芯的γ值和TCON的γ值，由于TCON的γ值是由屏驱动板的特性决定的，即显示器的TCON的γ值是固定的，因此，对画质图效的调整实际上就是对机芯的γ值的调整。一般来说，对画质图效进行调整是对不同的灰阶进行调整，由于灰阶通常分为256个不同的灰阶，不同的灰阶下达到目标画质时的整机的γ值不一定相同，即机芯的γ值不一定相同。由于整机的γ值可以较方便的测得，且画质图效相同即整机的γ值相同，因此，待调试样机相对于标准样机而言，达到相同画质图效时，仅机芯的γ值不同，而在调试完成时标准样机机芯的γ值已知，TCON的γ值可以由机芯的γ值和/或整机的γ值的关系表示，即只有待调试样机机芯的γ值未知；调整待调试样机机芯使预设灰阶下待调试样机整机的γ值达目标值，并将此时机芯的γ值作为所述预设灰阶下的γn值；即排除不方便测量的TCON的γ值的影响。
步骤S20，根据预设算法、所述γn值及同一灰阶下标准样机的γ0 值、γ0’值计算待调试样机的γn’值；
如前所述，只有待调试样机机芯的γ值未知，而整机的γ值包括机芯的γ值和TCON的γ值，因此，可以根据调整待调试样机及标准样机的整机的γ值与机芯的γ值和TCON的γ值的关系通过数学运算处理得到预设算法，即将待调试样机机芯的γ值用待调试样机整机的γ值和TCON的γ值表示，待调试样机整机的γ值和TCON的γ值可以用标准样机的整机的γ值与机芯的γ值表示，也就是用标准样机的整机的γ值与机芯的γ值表示待调试样机机芯的γ值(预设算法)，而标准画质样机机芯的γ值(γ0值、γ0’值)已知，待调试样机的γn值也可以通过调试得到，则根据预设算法即可计算得到待调试样机的γn’值；其中，γ0值为使标准样机整机γ值达目标值时机芯的γ值，γ0’值为使标准样机画质达到目标画质时机芯的γ值，γn值为使待调试样机整机γ值达目标值时机芯的γ值，γn’值为使待调试样机达到标准样机目标画质时机芯的γ值。
步骤S30，根据所述γn’值调整待调试样机的画质；
其中，γ0值为使标准样机整机γ值达目标值时机芯的γ值，γ0’值为使标准样机画质达到目标画质时机芯的γ值，γn值为使待调试样机整机γ值达目标值时机芯的γ值，γn’值为使待调试样机达到标准样机目标画质时机芯的γ值。
调整待调试样机机芯使该灰阶下机芯的γ值为γn’值，从而实现对画质图效的调整，由于此时待调试样机的整机的γ值与标准样机的整机的γ值相同，即待调试样机与标准样机的画质图效相同。传统的画质图效调整方式，是直接将标准样机的机芯的γ值拷贝到待调试样机，当待调试样机与标准样机的TCON的γ值不同时，即产品间的性能存在差异时，待调试样机的整机的γ值将与标准样机的整机的γ值不相同，即画质图效不相同。通过对每一台待调试样机的机芯的γ值进行适应性的计算从而调整画质图效，使得每一台待调试样机都能达到与标准样机相同的画质图效，不依赖于部品的一致性，画质图效调整简单高效。
本实施例通过对每一台待调试样机的机芯的γ值进行适应性的 计算从而调整画质图效，使得每一台待调试样机都能达到与标准样机相同的画质图效，不依赖于部品的一致性，画质图效调整简单高效。
参照图2，图2为本发明显示器画质图效调整的方法的第二实施例的流程示意图。基于上述显示器画质图效调整的方法的第一实施例，所述方法还包括：
步骤S40，获取整机γ值与机芯γ值的函数关系，及标准样机的机芯γ值与待调试样机的机芯γ值的函数关系；
步骤S50，通过对函数关系进行运算处理得到用于计算待调试样机γn’值的预设算法。
获取整机γ值与机芯γ值的函数关系，及标准样机的机芯γ值与待调试样机的机芯γ值的函数关系；通过对函数关系进行运算处理得到用于计算待调试样机γn’值的预设算法。一实施例中，预设算法的计算过程如下，以整机γ值的目标值为2.2为例进行描述，当然，整机γ值的目标值也可以为其他任意值；在灰阶n下，将标准样机的TCON的γ值记为γT0，整机γ值达2.2时的机芯的γ值为γ0值，当机芯的γ值为γ0’时，标准样机画质达到目标画质，整机γ值为a；将待调试样机的TCON的γ值记为γTn，整机γ值达2.2时的机芯的γ值为γn值，当待调试样机的整机γ值也为a时，待调试样机的画质达到标准样机目标画质，此时机芯的γ值为γn’；上述整机γ值与机芯γ值和TCON的γ值的函数关系表述如下：
n^(γ0’·γT0)＝n^a……(1)
n^(γ0·γT0)＝n^2.2……(2)
n^(γn’·γTn)＝n^a……(3)
n^(γn·γTn)＝n^2.2……(4)
通过上述公式(1)和(3)、(2)和(4)可以得到：
n^(γ0’·γT0)＝n^(γn’·γTn)……(5)
n^(γ0·γT0)＝n^(γn·γTn)……(6)
即
γ0’·γT0＝γn’·γTn……(7)
γ0·γT0＝γn·γTn……(8)
由公式(7)和(8)可得：
γ0’/γ0＝γn’/γn……(9)
即
γn’＝γ0’·γn/γ0……(10)
上述公式(10)即为预设算法，通过公式(10)可以知道，只要标准样机的γ0、γ0’确定，及待调试样机的γn确定，待调试样机的γn’就确定下来了。而γn’正是为达到标准样机相同画质效果，需要调整到的机芯的γ值。通过预设算法即可简单方便的得到待调试样机的γn’值，即用于使待调试样机达到标准样机相同的画质图效的机芯的γ值。
本实施例通过整机γ值与机芯γ值的函数关系、标准样机的机芯γ值与待调试样机的机芯γ值的函数关系，得到用于计算待调试样机的γn’值的预设算法，通过预设算法即可简单方便的得到待调试样机的γn’值，即用于使待调试样机达到标准样机相同的画质图效的机芯的γ值。
参照图3，图3为本发明显示器画质图效调整的方法的第三实施例的流程示意图。基于上述显示器画质图效调整的方法的第二实施例，所述步骤S10之前，还包括：
步骤S60，调整机芯使预设灰阶下标准样机整机的γ值达目标值，并将此时的机芯γ值作为该预设灰阶下的γ0值；
步骤S70，调整机芯使预设灰阶下标准样机画质达到目标画质，并将此时的机芯γ值作为该预设灰阶下的γ0’值；
步骤S80，将标准样机的γ0值和γ0’值输入待调试样机。
如前所述，要通过预设算法得到待调试样机的γn’值需要知道标准样机的γ0值、γ0’值及待调试样机的γn值，γ0值和γ0’值是通过对标准样机进行调整得到的，调整机芯使预设灰阶下标准样机整机的γ值达目标值，并将此时的机芯γ值作为该预设灰阶下的γ0值；调整机芯使预设灰阶下标准样机画质达到目标画质，并将此时的机芯γ值作为 该预设灰阶下的γ0’值；在得到γ0值和γ0’值后，将标准样机的γ0值和γ0’值输入待调试样机，则只需要在对应的灰阶下调整待调试样机，使待调试样机整机的γ值达目标值，再通过预设算法即可得到待调试样机的γn’值；标准样机的γ0值和γ0’值可以批量输入到同一批次生产的待调试样机中，从而可以对批量的待调试样机进行画质图效调整。
本实施例预先获得标准样机的γ0值和γ0’值，再将γ0值和γ0’值输入待调试样机，从而可以对批量的待调试样机进行画质图效调整。
参照图4，图4为本发明显示器画质图效调整的方法的第四实施例的流程示意图。基于上述显示器画质图效调整的方法的第三实施例，所述方法还包括：
步骤S90，根据灰度等级的高低设置预设灰阶对应的整机γ值的目标值。
画质图效的调整并不仅仅是调整机芯γ值，彩色等也要调。由于，通常灰度分为0～255共256个灰度，一般而言灰度越高，显示的色彩越丰富，画面也越细腻，更易表现丰富的细节。但是，当灰阶过低时，为了提高对比度，需要提高整机γ的值，例如，在灰度等级较高时，整机γ值设置为2.2，在灰阶过低时，把整机γ值调到2.4等。根据灰度等级设置预设灰阶对应的整机γ值的目标值，对于灰度等级的划分依据，可以是根据调试过程中画面对比度的需求确定，也可以是根据经验值等方式确定，例如，将0～10灰度等级下的预设灰阶对应的整机γ值的目标值设置为2.4，将11～255灰度等级下的预设灰阶对应的整机γ值的目标值设置为2.2等。根据灰度等级设置预设灰阶对应的整机γ值的目标值，可以提高画质图效的对比度等。
本实施例根据灰度等级设置预设灰阶对应的整机γ值的目标值，可以提高画质图效的对比度等。
参照图5，图5为本发明显示器画质图效调整的方法的第五实施例的流程示意图。基于上述显示器画质图效调整的方法的第四实施 例，所述方法还包括：
步骤S100，当调整机芯后未达到所述γn’值时，发送报警提示信息。
由于γn’值是根据预设算法计算得到的，而批量生产的产品间存在性能差距，有些显示器可能与标准画质样机的性能差距较小，此时，计算得到的γn’值与标准样机的γ0’值差距也较小，而有些则可能差距较大，此时，计算得到的γn’值与标准样机的γ0’值差距也较大。机芯的γ值有一个调整范围，当计算得到的γn’值与标准样机的γ0’值差距较大(超出机芯的γ值的调整范围)时，待调试样机机芯的γ值不一定能调整到该计算得到的γn’的值，此时，可以通过发送报警提示信息等方式进行提醒，以确定该待调试样机是否需要更换硬件等，以保证每一台显示器都能调整到标准样机目标画质的水平。
本实施例当调整机芯后未达到所述γn’值时，发送报警提示信息，以便工作人员对显示器进行进一步处理，保证每一台显示器都能调整到标准样机目标画质的水平。
本发明进一步提供一种显示器画质图效调整的装置。
参照图6，图6为本发明显示器画质图效调整的装置的第一实施例的功能模块示意图。
在一实施例中，所述显示器画质图效调整的装置包括：调整模块10及计算模块20。
调整模块10，用于调整待调试样机机芯使预设灰阶下待调试样机整机的γ值达目标值，并将此时机芯的γ值作为所述预设灰阶下的γn值；
显示器类的产品，为了使画质图效相同，在生产阶段要严格控制部品的一致性，缩小批量生产的产品间的性能差距，并以标准样机为标准对待调试样机进行调试，使待调试样机都能达到或接近标准样机的画质图效。当整机的γ值达到使画质处于最佳视觉状态时，即使画质达到目标画质，而整机的γ值包括机芯的γ值和TCON的γ值，由于TCON的γ值是由屏驱动板的特性决定的，即显示器的TCON的γ 值是固定的，因此，对画质图效的调整实际上就是对机芯的γ值的调整。一般来说，对画质图效进行调整是对不同的灰阶进行调整，由于灰阶通常分为256个不同的灰阶，不同的灰阶下达到目标画质时的整机的γ值不一定相同，即机芯的γ值不一定相同。由于整机的γ值可以较方便的测得，且画质图效相同即整机的γ值相同，因此，待调试样机相对于标准样机而言，达到相同画质图效时，仅机芯的γ值不同，而在调试完成时标准样机机芯的γ值已知，TCON的γ值可以由机芯的γ值和/或整机的γ值的关系表示，即只有待调试样机机芯的γ值未知；调整待调试样机机芯使预设灰阶下待调试样机整机的γ值达目标值，并将此时机芯的γ值作为所述预设灰阶下的γn值；即排除不方便测量的TCON的γ值的影响。
计算模块20，用于根据预设算法、所述γn值及同一灰阶下标准样机的γ0值、γ0’值计算待调试样机的γn’值；
如前所述，只有待调试样机机芯的γ值未知，而整机的γ值包括机芯的γ值和TCON的γ值，因此，可以根据调整待调试样机及标准样机的整机的γ值与机芯的γ值和TCON的γ值的关系通过数学运算处理得到预设算法，即将待调试样机机芯的γ值用待调试样机整机的γ值和TCON的γ值表示，待调试样机整机的γ值和TCON的γ值可以用标准样机的整机的γ值与机芯的γ值表示，也就是用标准样机的整机的γ值与机芯的γ值表示待调试样机机芯的γ值(预设算法)，而标准画质样机机芯的γ值(γ0值、γ0’值)已知，待调试样机的γn值也可以通过调试得到，则根据预设算法即可计算得到待调试样机的γn’值；其中，γ0值为使标准样机整机γ值达目标值时机芯的γ值，γ0’值为使标准样机画质达到目标画质时机芯的γ值，γn值为使待调试样机整机γ值达目标值时机芯的γ值，γn’值为使待调试样机达到标准样机目标画质时机芯的γ值。
所述调整模块10，还用于根据所述γn’值调整待调试样机的画质；
其中，γ0值为使标准样机整机γ值达目标值时机芯的γ值，γ0’值为使标准样机画质达到目标画质时机芯的γ值，γn值为使待调试样机整机γ值达目标值时机芯的γ值，γn’值为使待调试样机达到标准样 机目标画质时机芯的γ值。
调整待调试样机机芯使该灰阶下机芯的γ值为γn’值，从而实现对画质图效的调整，由于此时待调试样机的整机的γ值与标准样机的整机的γ值相同，即待调试样机与标准样机的画质图效相同。传统的画质图效调整方式，是直接将标准样机的机芯的γ值拷贝到待调试样机，当待调试样机与标准样机的TCON的γ值不同时，即产品间的性能存在差异时，待调试样机的整机的γ值将与标准样机的整机的γ值不相同，即画质图效不相同。通过对每一台待调试样机的机芯的γ值进行适应性的计算从而调整画质图效，使得每一台待调试样机都能达到与标准样机相同的画质图效，不依赖于部品的一致性，画质图效调整简单高效。
本实施例通过对每一台待调试样机的机芯的γ值进行适应性的计算从而调整画质图效，使得每一台待调试样机都能达到与标准样机相同的画质图效，不依赖于部品的一致性，画质图效调整简单高效。
参照图7，图7为本发明显示器画质图效调整的装置的第二实施例的功能模块示意图。所述显示器画质图效调整的装置还包括获取模块30及算法模块40。
所述获取模块30，用于获取整机γ值与机芯γ值的函数关系，及标准样机的机芯γ值与待调试样机的机芯γ值的函数关系；
所述算法模块40，用于通过对函数关系进行运算处理得到用于计算待调试样机γn’值的预设算法。
获取整机γ值与机芯γ值的函数关系，及标准样机的机芯γ值与待调试样机的机芯γ值的函数关系；通过对函数关系进行运算处理得到用于计算待调试样机γn’值的预设算法。一实施例中，预设算法的计算过程如下，以整机γ值的目标值为2.2为例进行描述，当然，整机γ值的目标值也可以为其他任意值；在灰阶n下，将标准样机的TCON的γ值记为γT0，整机γ值达2.2时的机芯的γ值为γ0值，当机芯的γ值为γ0’时，标准样机画质达到目标画质，整机γ值为a；将待调试样机的TCON的γ值记为γTn，整机γ值达2.2时的机芯的γ值 为γn值，当待调试样机的整机γ值也为a时，待调试样机的画质达到标准样机目标画质，此时机芯的γ值为γn’；上述整机γ值与机芯γ值和TCON的γ值的函数关系表述如下：
n^(γ0’·γT0)＝n^a……(1)
n^(γ0·γT0)＝n^2.2……(2)
n^(γn’·γTn)＝n^a……(3)
n^(γn·γTn)＝n^2.2……(4)
通过上述公式(1)和(3)、(2)和(4)可以得到：
n^(γ0’·γT0)＝n^(γn’·γTn)……(5)
n^(γ0·γT0)＝n^(γn·γTn)……(6)
即
γ0’·γT0＝γn’·γTn……(7)
γ0·γT0＝γn·γTn……(8)
由公式(7)和(8)可得：
γ0’/γ0＝γn’/γn……(9)
即
γn’＝γ0’·γn/γ0……(10)
上述公式(10)即为预设算法，通过公式(10)可以知道，只要标准样机的γ0、γ0’确定，及待调试样机的γn确定，待调试样机的γn’就确定下来了。而γn’正是为达到标准样机相同画质效果，需要调整到的机芯的γ值。通过预设算法即可简单方便的得到待调试样机的γn’值，即用于使待调试样机达到标准样机相同的画质图效的机芯的γ值。
本实施例通过整机γ值与机芯γ值的函数关系、标准样机的机芯γ值与待调试样机的机芯γ值的函数关系，得到用于计算待调试样机的γn’值的预设算法，通过预设算法即可简单方便的得到待调试样机的γn’值，即用于使待调试样机达到标准样机相同的画质图效的机芯的γ值。

所述输入模块50，用于将标准样机的γ0值和γ0’值输入待调试样机。
如前所述，要通过预设算法得到待调试样机的γn’值需要知道标准样机的γ0值、γ0’值及待调试样机的γn值，γ0值和γ0’值是通过对标准样机进行调整得到的，调整机芯使预设灰阶下标准样机整机的γ值达目标值，并将此时的机芯γ值作为该预设灰阶下的γ0值；调整机芯使预设灰阶下标准样机画质达到目标画质，并将此时的机芯γ值作为该预设灰阶下的γ0’值；在得到γ0值和γ0’值后，将标准样机的γ0值和γ0’值输入待调试样机，则只需要在对应的灰阶下调整待调试样机，使待调试样机整机的γ值达目标值，再通过预设算法即可得到待调试样机的γn’值；标准样机的γ0值和γ0’值可以批量输入到同一批次生产的待调试样机中，从而可以对批量的待调试样机进行画质图效调整。
本实施例预先获得标准样机的γ0值和γ0’值，再将γ0值和γ0’值输入待调试样机，从而可以对批量的待调试样机进行画质图效调整。
